Shopping Cart Question with Cookies!

[wkohusjr]

I'm passing cookies from one page to another.  Then I'm taking the value of a drop down menu (for quantity) the Price (a cookie) and doing the math to get the total.  My submit buttons will calculate and print the total into a <td>. 

 

My issue is when I have two items once I click submit it will remove the value of the one and calculate and print the other.

 

Any help would be greatly appreciated!

                global $tax;
                $tax = .06;
                
                if (isset($_COOKIE['shoe1'])) {
                    print "<tr><td>";

                    print "<img src=\"Images/1.jpg\" width=\"100px\" height=\"75px\">";

                    print "</td><td>";

                        echo $_COOKIE['shoe1']['Description'];

                    print "</td><td>";

                        echo $_COOKIE['shoe1']['Item#'];

                    print "</td><td>";

                        echo "$" . $_COOKIE['shoe1']['Price'];

I have not tested it...

global $tax;
				
                $tax = .06;
                
				
				//You should make each item added go into one cookie as an array
				//example say i add shoe 2 and three this is what is could look like
				//$_COOKIE['Products']['shoe1'] = array('Price' => '', 'Description' => '');
				//$_COOKIE['Products']['shoe2'] = array('Price' => '', 'Description' => '');
				
				//then you can run an foreach loop
				if(!empty($_COOKIE['Products'])){
					
					$price = 0; //scope
					$total = 0; //scope
					foreach($_COOKIE['Products'] as $Product => $Info){
						
						print "<tr><td>";
